(Rac)-Ketoconazole
(Rac)-Ketoconazole Rac)-R 41400) is an antifungal imidazole compound with oral activity. (Rac)-Ketoconazole interferes with ergosterol synthesis by inhibiting cytochrome P450-dependent 14α-sterol demethylase (CYP51), a key enzyme on the fungal cell membrane, leading to membrane dysfunction and ultimately inhibition of fungal growth and reproduction. (Rac)-Ketoconazole is indicated for studies of fungal infections.
